Description of the problem:
It’s tough.
This error sometimes occur sometimes does not. And it can occur at any trial in a block, which means sometimes the condition file was imported normally. It doesn’t seem to be a problem with the code itself. And I can’t get any effective error information from the console record online. It just said the problem happened when importing the condition file…
I checked this in the psychopy crib sheet. However, I didn’t put any variable with $. I am not sure if the condition file is too large. It’s only 19KB. My loop is like this:
Everytime the code select the condition file and select one row from the condtion file.
